T0 all wh-om it may concern.'

Be it known that I, Pinnen D. SGHENCK, a citizen of the United States,and a resident ot Dayton, in the county ot' Montgomery and State ofOhio, have made a new and useful invention in Improvements in AdjustableBrackets, of which the following is a specification.

The invention relates to adjustable brackets, and particularly bracketsfor supporting the guides lor piece goods in textile plants, such guidesbeing known in the art as pot eyes. These guides or pot eyes are set atdifferent angles, and the principal object et the present invention isthe provision of a bracket of cheap simple construction which can bereadily adjusted for any angle at which the guide may be set. Oneembodiment of the invention is shown in the accompanying drawings,wherein,

Figure l is a plan view el' the bracket. Fig. 2 is a side elevation. AndFig. 3 is an end elevation.

Briefly stated, the device comprises a pair et cooperating members inthe term of castings, one of which is lixed and has a U shaped clampingarch or holder, andthe other ot which comprises a hollow base or spherefitting in said holder and provided with a. pair of perforated l'eet towhich the pot eye is secured. The movable member is clamped in anydesired position of adjustment by means ol a pair oi' bolts extendingthrough the walls of the U shaped holder and engaging the surface oifthe ball. The ,[ixed member includes a base plate provided with aconcave recess in which the ball lits., and such recess in connectionwith the bolts give a secure three point support for the ball.

Referring to the drawings, l is the base of the fixed bracket member,which plate is provided with the circular projection 2 having a concaverecess 3 at its center for receiving the ball or sphere et the movablebracket member as hereinafter described. Extending over the projection 3is the arch or U shaped holder 4t, reinforced at its ends by the ribsv5, 5, which merge into the sides of the projection 2. The walls of theholder 4 are provided with a pair of pertorations Serial No. 669,598.

carrying the clamping bolts 6, 6, and -the base plate l is provided atits corners with the perforations 7 whereby the plate may be held inlixed position by means ot bolts or screws.

The movable bracket member consists of the hollow ball or sphere 8 andthe laterally projecting portion 9 provided with the reet l0, l0, havingthe slots 11, l1 through which suitable bolts may be passed forsupporting the pot eyes. The surface of the sphere or ball 8 fits intothe concave recess 3 in the base plate and is securely clamped in anydesired position of adjustment'by means of the bolts 6, 6. Thisarrangement provides 'for -a Wide range ot' adjustment of the movablebracket member, and the recess l in connection with the two boltspositioned as indicated, give a secure three point support in allpositions ot adjustment. i

The ball or sphere is made hollow to lighten the device, the hole 12being provided to permitoii' the removal ot' the core employed incasting. As beto-re indicated, both bracket members are castings, and asthey require no machining, aside from the tapping ot the holes for theclamping bolts or' screws (5, 6, the cost of the device is reduced to aminimum. At the same time it has the strength necessary for the purposefor which it is designed and may be adjusted in every direction withoutdiliiculty.

lhat I claim is:

In combination in a bracket, a cast meinher comprising a base having arecess in the tace thereof, and an inverted U-shaped member with itsends integral with such base and its concave portion extending over saidrecess in opposition thereto, an adjustable cast member including Kahollowball lying in said U-shaped member and engaging said recess, and asupporting portion projecting laterally from the ball, and a pluralityof clamping bolts threaded through the curved portion of the U-shapedmember and engaging said ball and lyingradially with respect to saidball.

In testimony whereof, I have hereunto subscribed my name this 17th dayoi W October, 1928.
